I have read a similar thread but I couldn't figure out a solution so far.

Here's the situation: I imported all my Outlook Express messages in Barca Pro 1.4.0.1000. Albeit most of my attached files (Ms Word documents) correctly show up in the attachment pane with their own extension, some of them don't, for no apparent reason. They are displayed inline as .txt files and appear unreadable even if saved as .doc files.

In my "attachment encoding options" all fields are unticked (attachments are not to be encoded indside the message).
